Title: Web printing apparatus
IPC: B41F13/14
Filed: 1966-06-23
Abstract: 1,125,352. Rotary web-fed printing machines. E. KUGLER. 23 June, 1966, No. 28035/66. Heading B6C. A machine for multi-impression or multicolour printing on a web of plastics material comprises printing stations A and B, each of which includes a split printing cylinder 35 having two separately actuable axially displaced portions 35a, 35b. Drive means are operatively connected to each cylinder portion such that a web 10 is passed over successive portions 35b of stations A and B before reversal by turnbars 101, 102 for passage back through the machine over successive portions 35a. Means are provided for causing two-directional relative movement between the web 10 and the cylinder portions for registering the printing on the web, the axial registration being accomplished by adjusting the angled position of the turnbars whilst circumferential registration is effected through the provision of a differential mechanism associated with each cylinder portion. If required, the web 10 may be wide enough to cover both portions 35a, 35b at each station whilst moving in a single passage through the machine. The machine may also be used either to print two side-by-side single passage webs or to print a single web with two impressions on each side, the latter operation being effected by so arranging the turnbars that the web is inverted between runs.

Title: Multi-position rotary electric switch device
IPC: G07F17/30
Filed: 1958-09-02
Abstract: 870,133. Mechanical switches without quick action; press-button retractive switches. DURANT, L. A. Sept. 2, 1958, No. 28184/58. Class 38 (5). A panel 1 carries a button 8 for energizing a circuit selected by two ten-way rotary switches controlled by knobs 2 and 3 respectively. The arrangement is such that button 8 cannot be depressed while either knob is being moved, and an electromagnet is provided to prevent any of the switches being effective while the electromagnet is energized. Each knob has a portion of translucent material carrying indices as shown for registration with fixed marks 9 and 10 on the panel 1, and windows 11 and 12 in the panel serve to illuminate the selected indices by means of lamps not shown. The button 8 contains a retractive spring, and a U-shaped member 18 is slidably positioned over a bushing 15 which reciprocates with button 8. A spring 19 causes frictional engagement between member 18 and bushing 15 so that depression of button 8 moves member 18 and closes the contacts of spring blades 23, 24. The knobs 2 and 3 rotate assemblies 56 and 57 of spring-loaded brushes over fixed contact plates 54 and 55 respectively, and are located in selected positions by spring-loaded detent members 27 and 28 which are pivoted at 29 and 30 and carry rollers 31 and 32 engaging star wheels 25 and 26 as shown. The free ends of members 27 and 28 are shaped to move over the end 14 of the button device whenever knobs 2 and 3 are moved from a rest position (Figs. 7 and 10, not shown) and thereby prevent operation of the button. An electromagnet (Figs. 8 and 9, not shown) is mounted so that when energized its armature moves a plate 42 and an arm 49 towards panel 1. The arm 49 engages one leg of member 18 and moves it out of locking engagement with bushing 15 such that depression of button 8 moves the bushing freely through member 18 and blades 23, 24 cannot be closed. The end 52 of a locking plate carried on plate 42 passes into the path of detent members 27 and 28 (see Fig. 6) to prevent rollers 31, 32 from leaving their respective star wheels 25 and 26, thus locking the rotary switches. The plate 52 is slidable on plate 42 against the action of a spring 51 so that should either knob 2 or 3 be held to make its detent member grip plate 52 the armature can restore upon de-energization of the electromagnet and as soon as the knob is released spring 51 withdraws plate 52.

Patent GB-772192-A (GB)
Title: Improvements in or relating to the production of thyrotropin preparations
IPC: A61K38/24
Filed: 1954-10-04
Abstract: Thyrotropin is selectively precipitated from an aqueous solution of thyrotropin and non-thyroid stimulating proteins from pituitary material by the addition of a mono-hydroxy alkane containing less than 4 carbon atoms until the concentration of the said mono-hydroxy alkane is from 5 to 35 per cent by volume. Ethanol is the preferred precipitating agent.  The fractionation is carried out at low temperatures preferably between -5 DEG C. and +5 DEG C.  The process is particularly adapted for separating thyrotropin from gonadotropin. The thyrotropin precipitate is purified by a process which involves forming a solution at pH 4, removing precipitates formed on the addition of acetone, until finally the thyrotropin is precipitated at an 80 per cent acetone concentration.  A detailed procedure of extraction and purification is described in the examples.

Title: Automatic brake adjusting mechanism
IPC: F16D65/09
Filed: 1963-07-19
Abstract: 1,011,465. Shoe drum brakes. KELSEY-HAYES CO. July 19, 1963 [July 30, 1962], No. 28677/63. Heading F2E. A brake assembly comprising first 12 and second 13 brake shoes with means 20 for moving them into engagement with a brake drum 10 has an anchor 49 for the first shoe with an adjustment operated by the second shoe but normally locked by a lever 80 which is releasable in response to excessive movement or wear in the first shoe. Torque-resisting members 40 fixed at 44 to the back plate 11 support the brake applying means 20 comprising hydraulic cylinders with pistons 21 separated by a spring 23, as well as the adjustable anchors 49 and have slots (Fig. 5, not shown), to receive the other ends of the shoe webs which are not engaged by the anchors 49. The shoe-ends are retained on the anchors by return springs 24. Washers 33, held by bolts 30 which pass through enlarged holes in the webs 18 and 19, retain the shoes movably on to the back plate 11. The threaded shank 50 of the adjustable anchor 49 screws into a bore in the torque member 40 and carries medially a disc 51 having peripheral teeth 52 and a knurled front face 53. A pawl-lever 61 controlled by a spring 64 is pivoted at 62 on the torque member 40 and is connected to the second shoe 13 by a link 67 with enlarged ends which passes freely through brackets 70 and 72 on the shoe and lever respectively. The locking lever 80 is pivoted on the back plate at 81 and is controlled by a spring 83 so that its serrated face 82 normally engages the knurled face 53 of the adjusting disc 51 to lock it. A pin 86 on the lever 80 protrudes through an oversize slot 87 in the shoe web. This pin does not contact the right-hand (see Fig. 1) edge of the slot 87 when the brake is applied, except when the shoe moves more than usual due to wear &c. Contact of the pin with the right-hand edge of the slot causes the face 82 of the lever 80 to move free of the knurled face of the adjusting disc 51 so that the latter is able to turn. The adjusting discs are only operated by the shoes when the brakes are applied with the wheels moving in reverse. Under such conditions the second shoe, now leading, causes the lever 61 to lift its cranked end 60 off the teeth 52 of the adjusting disc to a position where it is cocked against the spring 64. On release of the brake the spring pulls down the lever with an inward bias on to a fresh tooth of the disc, thereby turning it before the lever 80, if already freed, can re-engage.
